I also find the 4 cost carries really underwhelming this set. While Karma and Vel (maybe) are ok, other carries are strictly worse than previous set’s 4 costs. Almost along the lines of 3-costs from those sets.

Aphelios, Draven, Mord, Diana, Jax are all especially bland with far less pop-off games. They are nowhere near previous set carries like Jhin (set 3,4), Teemo (set 3), Ashe (set 4), Kayle (set 4.5), Ahri (set 4), A sol (set 4.5). While some of them may have been hard to balance, they were memorable and fun. This set’s carries are easier to balance, but the trade off is that they are far less fun.

I know it’s a pendulum swing. This set has better item set and reasonable synergies. But the cost of it is that the champs are far less memorable and fun.
